Unless you've configure your web applications to recycle, then you should
see something in the Windows Event Log if the worker process servicing the
pool was shutdown unexpectedly. I think that takes care of (2)
(3) is not a problem *unless* the w3wp.exe process servicing the application
pool somehow terminates unexpectedly (meaning that everything stored
in-memory was lost). I suggest you look in your Windows Event Log for events
about this.
Otherwise, I suggest you start looking elsewhere. To maintain ASP session
state requires:
a) a ASPSession cookie value to be sent from the server to the client (check
this using a network sniffer like NetMon or Ethereal)
b) the browser to send the ASPSesion cookie back to the server on the next
request (again, check this using a network sniffer)
c) the server to recognise this as a valid, non-expired ASP Session ID
